ELISA Milestones & What’s next

By Blog, Working Group

As Linux continues to be a key component in safety-related applications, Enabling Linux in Safety Applications (ELISA) is an open source project that aims to create a shared set of tools and processes to help companies build and certify Linux-based safetycritical applications and systems. Launched in February 2019, ELISA works with Linux kernel and safety communities to agree on what users should consider when using Linux in safety-critical systems.

In 2023, ELISA increased the technical resources created for the Linux community, including a Seminar Series of no-cost, on-demand videos that provide overviews of a special focus and project workshops for community members who are interested in advancing the milestones and goals of the project. The ELISA Seminar series hosted sessions that many organizations hosted, including Red Hat about an open source tool, tentatively named Basil, for tracing requirements, code, and tests; AMD about Xen safety certification; the Linux Foundation with AlektoMetis about automating adherence to safety profiles after fixing vulnerabilities; and the Boeing Company about DO-178C Level D certified Linux and NASA.

Two in-person workshops in Berlin and Munich brought together industry thought leaders and open source community members to discuss all safety-related issues, challenges, and next steps for the project. The project has several dedicated Working Groups (WGs) that provide resources for system integrators to apply and use to qualitatively and quantitatively analyze their systems:

  • Aerospace WG is busy surveying aerospace’s state of the art on using Linux and the associated certification approach and equivalent Design Assurance Level and identifying the challenges to adopting Linux in aerospace and candidate use cases using Linux.
  • Architecture WG is adopting the ks-nav tool set to implement and expand the STPA approach within the kernel.
  • Linux Features WG analyzed the potential and challenges of real-time safety-critical systems and presented their work at the Embedded Open Source Summit.
  • Medical Devices WG set out to discover the Linux kernel subsystems that OpenAPS used, shared key findings, and upstreamed the workload tracing guide.
  • Open Source Engineering Process WG documented how to apply a safety analysis process based on STPA suitable for Linux and other OSS use.
  • Systems WG shared the work on creating a reproducible example system consisting of Linux, Xen, and Zephyr on real hardware at the Linux Plumbers Conference.
  • Tools WG has enabled Continuous Integration.

To kick off the new year, ELISA Working Group leads will be giving an annual update next week. The updates will include the following topics:

  • A recap of milestones in 2023
  • Current focus and activities
  • What’s coming up in 2024 and areas and opportunities for collaboration
  • Onboarding resources and how to get involved

This is a great opportunity to get up to speed with what each of the Working Group is working on and how you can participate and contribute this year. For more details and to register to attend please click here: https://elisa.tech/event/working-group-annual-updates/.

Putting Linux into Context – Towards a reproducible example system with Linux, Zephyr & Xen 

By Ambassadors, Blog, Industry Conference

Last week, developers from around the world traveled to Richmond, Virginia for the annual Linux Plumbers Conference. Hosted at the Omni Richmond Hotel on November 13-15, the event was mostly in-person with a live-streaming element for those who couldn’t make it.

Philipp Ahmann, Product Manager for Embedded Open Source at Robert Bosch GmbH and Chair of the ELISA Project Technical Steering Committee (TSC), was at the event and gave presentation titled, “Putting Linux into Context – Towards a Reproducible Example System with Linux, Zephyr & Xen.” You can find his presentation video and PPT  below:

 

Demos on embedded systems using Linux are plentiful, but when it comes to reproducing them, things get complicated. Additionally, on decent embedded systems Linux is only one part of the system and interacts with real-time operating systems and virtualization solutions. This makes reproduction even harder.

Within the Linux Foundation’s ELISA project, we started to create a reproducible example system consisting of Linux, Xen, and Zephyr on real hardware. This is the next step after we achieved a reproducible system with a pure Linux qemu image.

The idea is to have documentation, a continuous integration including testing, which can be picked up by developers to derive and add their own software pieces. In this way they should be able to concentrate on their use case rather than spending effort in creating such a system (unless they explicitly want this). We also show how to build everything from scratch. The assumption is that only in this way it is possible to get a system understanding to replace elements towards their specific use cases.

We had challenges finding good hardware, tools, freely available GPU drivers and more and we are still not at the end. A good system SBOM is also creating additional challenges, although leveraging the Yocto build system has provided some advantages here.

While we are setting up the first hardware with documentation from source to build to deployment and testing on embedded hardware, we aim to have at least two sets of all major system elements like Linux flavor, a choice of virtualization technique, real-time OS and hardware. Only when software elements and hardware can be exchanged, we identify clear interfaces and make a system reproducible and adoptable.

Open Questions are:

  • What will be a good next hardware to extend this PoC scope?
  • Where do open source, security, safety, and compliance come best together?
  • Which alternative real-time operating systems and virtualization should be incorporated?

Finding the Path from Embedded to Edge using Product LinesSteffen Evers, Bosch.IO & Philipp Ahmann, Robert Bosch GmBH

Linux is used for many embedded device classes today. However, it is increasingly desirable to connect these devices with each other and with the cloud. Embedded container technology can be used to make this easier by merging server/cloud and embedded technologies. However, it also leads to more challenges e.g. in respect to security, safety, traceability, and SBOMs. Using Linux across multiple device classes and product lines, and adding cloud technology, causes the complexity and efforts to explode.

In this talk, we describe how Bosch, and others, use embedded containers and “reference systems” to avoid redundant work and get a large number of embedded projects under control.

A reference system is an adjustable compilation of tools along with a pre-configured bundle of packages for a common use case and defined set of devices. This reuse significantly reduces development and maintenance costs, and speeds up the time to market. In this way, reference systems can form the base for your product lines.

Bosch uses the in-house Debian-based embedded distribution “Apertis” as the basis for several reference systems, e.g. for automotive infotainment systems. In doing so we push as many efforts as possible from individual projects into Apertis, as the meta-layer. Thereby, the users can focus more on the actual functionality and applications. e.g. one issue that we have addressed in the context of software management is the handling of GPLv3 in embedded devices. Another topic has been mainline support for kernel drivers.

BOF: SBOMs for Embedded Systems: What’s Working? What’s Not? – Kate Stewart

With the recent focus on improving Cybersecurity in IoT & Embedded, the expectation that a Software Bill of Materials (SBOM) can be produced, is becoming the norm. Having a clear understanding of the software running on an embedded system, especially in safety critical applications,  like medical devices, energy infrastructure, etc. has become essential.  Regulatory authorities have recognized this and are starting to expect it as a condition for engagement.  This BOF will provide an overview of the emerging regulatory landscape, as well as examples of how SBOMs are already being generated today for embedded systems by open source projects such as Zephyr, Yocto and others,  followed by a discussion of the gaps folks are seeing in practice, and ways we might tackle them.

Static Partitioning with Xen, LinuxRT, and Zephyr: A Concrete End-to-end Example – Stefano Stabellini, AMD

Static partitioning enables multiple domains to run alongside each other with no interference. They could be running Linux, an RTOS, or another OS, and all of them have direct access to different portions of the SoC. In the last five years, the Xen community introduced several new features to make Xen-based static partitioning possible. Dom0less to start multiple static domains in parallel at boot, and Cache Coloring to minimize cache interference effects are among them. Static inter-domain communications mechanisms were introduced this year, while “ImageBuilder” has been making system-wide configurations easier. An easy-to-use complete solution is within our grasp. This talk will show the progress made on Xen static partitioning. The audience will learn to configure a realistic reference design with multiple partitions: a LinuxRT partition, a Zephyr partition, and a larger Linux partition. The presentation will show how to set up communication channels and direct hardware access for the domains. It will explain how to measure interrupt latency and use cache coloring to zero cache interference effects. The talk will include a live demo of the reference design.

RTLA: Real-time Linux Analysis Toolset – Daniel Bristot De Oliveira, Red Hat

Currently, Real-time Linux is evaluated using a black-box approach. While the black-box method provides an overview of the system, it fails to provide a root cause analysis for unexpected values. Developers have to use kernel trace features to debug these cases, requiring extensive knowledge about the system and fastidious tracing setup and breakdown. Such analysis will be even more impactful after the PREEMPT_RT merge. To support these cases, since version 5.17, the Linux kernel includes a new tool named rtla, which stands for Real-time Linux Analysis. The rtla is a meta-tool that consists of a set of commands that aims to analyze the real-time properties of Linux. Instead of testing Linux as a black box, rtla leverages kernel tracing capabilities to provide precise information about latencies and root causes of unexpected results. In this talk, Daniel will present two tools provided by rtla. The timerlat tool to measure IRQ and thread latency for interrupt-driven applications and the osnoise tool to evaluate the ability of Linux to isolate workload from the interferences from the rest of the system. The presentation includes examples of how to use the tool to find the root cause analysis and collect extra tracing information directly from the tool.

ELISA Welcomes 3 Mentees!

By Blog, Mentorship, Working Group

The Linux Foundation has had a robust mentorship program for years that invests in new talent and diversity that helps the open source community – no matter what the focus or project – thrive as a whole. Since its formal launch in 2019, the LFX Mentorship has graduated more than 190 mentees and has hosted almost 100 mentorship programs. 

This Spring, the ELISA Project is hosting two mentorships that will help developers gain real-world knowledge in a hands-on learning experience with Linux and open source. It also provides a more defined path for ELISA to connect with the next generation to inject more talent into their developer base.

The Spring Mentorship session, which kicked off in March, paired mentees with leaders from Codethink, the Linux Foundation and Mobileye. The ELISA Project is excited to welcome  Irenge Jules Bashizi, Shefali Sharma and Wenhui Zhang as the newest mentees in the ELISA community. Please see below for more details about their mentorships and mentors. As they settle into their new roles, we hope to feature their mentorship journey in upcoming blog posts. 

Mentorship: Analysis of eBPF (extended Berkley Packet Filter) Verifier

To make eBPF programs “safe”, the Linux kernel validates all eBPF code before loading. However, the current validator has many known limitations, leading to rejection of working programs. 

Focus in this mentorship will be: 

  • In-depth analysis and review of the eBPF validator, and its use to validate eBPF programs.
  • Code enhancements to the validator to improve usability.
  • Identify use cases for kernel profiling in safety critical applications.
Elana Copperman

Mentor: Elana Copperman, Chair of the Linux Features for Safety-Critical Systems Working Group and System Safety Architect at Mobileye (part of Intel)

Elana provides support for designing safety features in Mobileye products, including system boot; drivers; and Linux infrastructure.

Mentorship: Discovering Linux kernel subsystems used by OpenAPS

OpenAPS is an open source Artificial Pancreas System designed to automatically adjust an insulin pump’s insulin delivery to keep Blood Glucose in a safe range at all times. It is an open and transparent effort to make safe and effective basic Automatic Pancreas System technology widely available to anyone with compatible medical devices who is willing to build their own system.

What happens when an OpenAPS workload runs on Linux? What are the subsystems and modules that are in active use when OpenAPS is running? What are the interactions between OpenAPS and the kernel when a user checks how much insulin is left in the insulin pump?

The ELISA Medical Devices Working Group set out to answer these questions. Understanding the kernel footprint necessary to run a workload helps us focus on the  subsystem and modules that make up the footprint for safety.

The mentee will:

  • Use Linux kernel tracing and strace tool to discover Linux kernel subsystems used by OpenAPS. 
  • Find Linux system calls supported on various architectures. 
  • Write a blog/whitepaper on the findings which will aid ELISA Medical Devices WG to focus on the  subsystem and modules that make up the footprint for safety.

By Announcement, Workshop

Register for the ELISA Spring Workshop on April 5-7 to Learn More

SAN FRANCISCO – March 23, 2022 –  Today, the ELISA (Enabling Linux in Safety Applications) Project, an open source initiative that aims to create a shared set of tools and processes to help companies build and certify Linux-based safety-critical applications and systems, announced a stronger ecosystem focused on automotive use cases with the addition of the Automotive Intelligence and Control of China (AICC), LOTUS Cars and ZTE.

“The ELISA ecosystem continues to grow globally with strong support from automakers across Asia and Europe,” Kate Stewart, Vice President of Dependable Embedded Systems at The Linux Foundation. “By leveraging the expertise of current and new ELISA Project members, we are defining the best practices for use of Linux in the automobiles of the future. “

Linux is used in all major industries because it can enable faster time to market for new features and take advantage of the quality of the code development processes. Launched in February 2019 by the Linux Foundation, ELISA works with Linux kernel and safety communities to agree on what should be considered when Linux is to  be used in safety-critical systems. The project has several dedicated working groups that focus on providing resources for System integrators to apply and use to analyze qualitatively and quantitatively on their systems.

The Automotive Working Group discusses the conditions and prerequisites the automotive sector needs to integrate Linux into a safety critical system. The group, which includes collaboration from ADIT, Arm, Codethink, Evidence (a part of Huawei), Red Hat and Toyota, focuses on actual use cases from the Automotive domain to derive the technical requirements to the kernel as a basis for investigation within the Architecture Workgroup and to serve as a blueprint for actual projects in the future. There is also close collaboration with Automotive Grade Linux, which results in a meta-ELISA layer enhancing the instrument cluster demo for safety relevant parts. As leaders in the automotive industry, AICC, LOTUS Cars and ZTE will most likely join the Automotive Working Group.

ELISA Ambassador: Elana Copperman

By Ambassador Spotlight, Ambassadors, Blog

ELISA Ambassadors are technical leaders who are passionate about the mission of the ELISA Project, recognized for their expertise in functional safety and linux kernel development, and willing to help others to learn about the community and how to contribute. 

Each month, we’ll put a spotlight on an ELISA Ambassador. Today, we’re excited to highlight Elana Copperman, PhD, ELISA ambassador, Chair of the Linux Features for Safety-Critical Systems (LFSCS) Working Group and TSC voting member.  Elana works as a System Safety Architect in Mobileye, an Intel company, designing features to support safety as well as security features in Mobileye vision products for the automotive domain.

Background Details:

As a System Safety Architect at Mobileye, Elana provides support for designing critical system features in Mobileye products, including system boot; drivers; and Linux infrastructure. Before working at Mobileye, she worked as a Security Architect for Cisco-Il (formerly NDS) and more recently as a security consultant for major European automotive concerns on behalf of various Israeli startups.  Most recently, merging with safety constraints in the automotive domain, to deploy secure as well as safe systems.  Her research interests focus on software engineering methodologies and security engineering.  

Q&A

How long have you been active in open source?

I have been involved in “open source” before it was formalized as we know it today.  During my time as an undergraduate student, online software source code was commonly shared as freeware.  In fact, even early Unix versions were provided at no cost to academics, and collaborative efforts were supported to some degree.  

My PhD research focused on Object-Oriented Programming, including some investigations on Java source code and features.  Open source software development, Linux in particular, has evolved since then, including many new challenges and opportunities.  For example, setting up and working with Apache Server over Linux OS in the early 1990’s.

Over the last 15 years, Linux has grown to what we know & love today, with its amazing powers.  As a system architect, I have been designing systems that empower Linux in embedded systems, first in Set-Top Boxes (for digital broadcasting) and currently in Automotive.

Tell us about your favorite open source project and what problems did it aim to solve?

My favorite open source project focused on security code review with ST (chip vendor) engineers for the optee code, which had been released to Linaro.  To see first-hand how open source aligns vendor, kernel and user requirements with features to resolve complex security challenges was mind-blowing. 

How long have you been active in the ELISA Project? 

I have been active in ELISA  for more than 2 years, with active participation in each of the Workshops since joining.  I have also presented talks related to Linux kernel features such as CRC pitfalls, eBPF verifier, isolation techniques, and kernel configurations related to safety.

What roles and/or working groups do you have or participate in?

I was the Chair of the Kernel Development Process Working Group, and am currently the new Linux Features for Safety-Critical Systems WG.  I am learning from the safety experts on board, and my primary contribution is to represent the viewpoint of the application designers and developers who will build Linux-based safety critical systems.  

Where do you see the ELISA Project in three years?

My dream for ELISA is to see a community of developers providing kernel modules which may be leveraged for use in safety critical systems.  For example, a suite of memory protection mechanisms derived from well defined requirements that may be deployed to protect safety-critical data.  Another example, which is in our planned agenda, are test suites for concurrency issues such as deadlock and race conditions, focusing on test plans derived from safety requirements.

What is the biggest strength of the ELISA community?

I think ELISA has matured since its early days and we are currently more structured in our analysis and goals.  Our strength is in current efforts to progress and making real contributions to the Linux kernel community.

What is the best piece of advice you have ever received?

Never give up.  Be flexible, adapt, adjust – but keep up the hard work.

What technology can you not live without? Why?

My home coffee machine.  Drop in for a fresh cup and you will know why.

What part of the world do you live in? Why do you love where you live?

I live in Israel, a tiny multicultural nation at the junction of 3 continents (Europe, Asia, Africa). It has also become a major highway for birds – and a pilgrimage site for bird watchers.  A wide variety of species can be viewed making their way south in the fall and back north in the spring.  Thomas Krumenacker (German journalist and photographer) wrote a book on “Birds in the Holy Land”. 

Now is a great time of year to take a trip to the Hula Valley Nature Reserve, to get a view of some of the estimated 500 million migrating birds passing over the Hula Valley and stopping by for a drink of water. This exemplifies the amazing diversity of the people and wildlife of our small fast-paced country.

3 Fun facts: 

  • My first computer was a PCJr, with 64 Kb of memory, and with virtually no hardware or software.  I had to install all my own hardware add-ons and get it to work, including etching bit maps for the Hebrew alphabet in memory and getting it to work from right to left.  After adding more and more components to the motherboard, one day it blew up.  But I had a lot of fun with it until that happened.

  • As a grad student at NYU, we had loads of fun playing with early internet protocols and collaboration tools, including gopher and kermit; getting our hands dirty  (“finger”) working with each other’s systems; and Mosaic (an early Web browser).  The crazy things we did over the internet taught me a lot about potential security issues related to networking.  This expertise was the foundation for my more recent work in security and safety engineering.
  • As chair of the Computer Department at the Jerusalem College, we aimed high but with a low budget. Trying to keep up to date with educational (i.e., no support or documentation) versions of closed source software was a real challenge.  I became adept at finding contacts working with major software vendors who were willing to break down the walls, expose the source code and support my customization for our needs.  In a sense, challenging proprietary software in open-source development mode …
